NEW YORK (CBSNewYork) — Zoe Koplowitz suffers from multiple sclerosis, but that has not stopped her from competing in the ING New York City Marathon for 25 years.

As 1010 WINS’ Gary Baumgarten reported, Koplowitz, 65, participated in the marathon again on Sunday. Each year, the steps become more difficult to take, but each year, she promises herself she will return the next.

“This is kind of like Tom and Huck setting out every year on a grand adventure,” Koplowitz said. “You always know what the destination you have in mind is, but no matter how many times you make the journey, it’s always new.”

Members of the Guardian Angels Safety Patrol accompanied Koplowitz as they always do, for the entire length of the marathon, no matter how long it takes.

Koplowitz was diagnosed with MS in her 20s, back when there were far less treatment options than there are today, according to the National MS Society. She said running the marathon was her way of reclaiming everything surrendered to multiple sclerosis over the years.”

Koplowitz uses two crutches to assist her through the 26.2-mile course. She manages to cross the finish line each time the morning after the race.
